We just released new categories within 'Babies & Kids' and 'Home & Garden' available for use for our Publisher Data Feed and Catalog API users.
Release Date: May 13, 2010 (Bizrate)
XML Feed: There will be new category files representing each new atomID. There will be fewer offers in related category files as offers are recategorized into the newly created categories.
XML API & Dynamic Content Assets: If you are making dynamic calls within either ‘Babies & Kids’ or ‘Home & Garden’, and not specifying a keyword, you may want to consider tuning your specified category to continue displaying your desired results.
